introduced into the human body by the bite of a mosquito. As a result 

 of the rapid multiplication of the parasite when it reaches the blood? 

 and the consequent destruction of the red blood corpuscles, anaemia sets 

 in and often terminates fatally. 



Probably many of the obscure diseases in our domestic animals are 

 due to Sporozoa. We certainly now know that the " Texas fever " or 

 " Red water " in cattle is a fever produced by a Haemosporidian, and 

 that some fatal epidemics in sheep and pigs are due to Sporozoa 

 (^Sarcosporidia) which secrete an active poison within the tissues of the 

 host. It may be noted that the author, Prof. Minchin, is inclined to 

 regard the Sporozoa as descendants of Rhizopod-like ancestors, a view 

 which is not shared by Biitschli and other authorities. 



To furnish an adequate account of the structure, life-histor}'', and 

 classification of the Infusoria, and limit it to sixty pages seems a difficult 

 task; for even since Biitschli's great work on that group appeared in 1889 

 a good many memoirs have been published, as will be seen from the list 

 of papers in the appendix. Yet Prof. Hickson has given us a very 

 readable and well illustrated article of the Infusoria, though he has not 

 added much that is actually new. 



The volume concludes with a useful Index, not only of the families, 

 genera and authors, but also of all the technical terms used.

We are glad to see that this useful guide-book has now reached a fourth 



edition. In addition to the matter usual in railway handbooks. Prof. 



Cole's account of the geology, and Mr. Praeger's of the botany of Co. 



Antrim, have been revised so as to direct the tourist's attention to the 



natural interests of the scenery through which he passes. But why are 



the animals of the district neglected } Surely the wonderful fauna of 



Lough Neagh is worth a few lines in such a Guide as this. The principal 



addition to former issues of the work is an excellently illustrated account 



of the Gobbins' Cliff-path, described in the Irish Naturalist a year ago.

We are glad to see that this Magazine has completed its second 



volume. Its success means that the honey industry is spreading in the 



country, and what a profitable source of income that may be can be 



learnt by all who will look carefully through the volume before us.
